TECHNICAL FIELD

The present disclosure relates to tailgates and, specifically, tosurfaces of a plastic glazing of a tailgate including textures and/orpatterns.

TECHNICAL BACKGROUND

Vehicles such as sports utility vehicles (“SUVs”), vans, hatchbacks, andthe like include a structural component known as a tailgate. Thetailgate is provided to open or close an opening formed at a rearportion of a vehicle. The tailgate is typically hinged to the mainvehicle body, for example, along its upper end, such that it can swingopen and close. Examples of tailgates include a rear door tailgate or atruck lid tailgate.

The tailgate may support one or more other vehicle components, such as arear glass window and one or more light assemblies (e.g., a supplementalbrake light, a puddle light). The tailgate may also be adjacent to bodycavities into which rear lamp units are inserted. These parts and otherparts may add to the cost and complexity of assembling a vehicle.

Light assemblies in vehicles, in particular, comprise a large number ofseparate components. For example, a typical vehicle may have severaldifferent types of lights, including, for example, parking lights, turnindicator lights, brake lights, and the like. Each of these lights maybe made from many parts. These parts add to the cost and complexity ofassembling a vehicle. Accordingly, as recognized in U.S. Pat. No.7,048,423 (“the '423 Patent”), it desirable to have a lighting assemblywith fewer parts. The '423 Patent discloses an integrated light assemblyincluding a plurality of lamps 210, 216 enclosed in a housing 202, whichmay serve as a lens for the lamps, and mounted on a substrate 204.Because the lamps 210, 216 share a common substrate and lens, theadditional cost of having a separate lamp assembly is eliminated. Thisstructure disclosed in the '423 Patent, however, has many drawbacks. Forone, because multiple lamps are mounted together in a single housingwithout sidewalls or reflectors for directing the angle of their light,the structure does not account for haziness issues. Moreover, if twolights of varying color are mounted in the housing, the structuredisclosed in the '423 Patent does not have a way of preventing coloroverlap. These drawbacks may limit the use of such a light assembly in avehicle under state and federal regulations governing vehicle lightingrequirements. Thus, while the '423 Patent discloses an integrated partfor a vehicle, its application may be limited.

Inhomogeneities such as seams and openings between separate vehiclecomponents may also add to the cost of assembling, sealing and/orinsulating an interior of the vehicle and/or its components. Moreoversuch seams and openings may cause aerodynamic inefficiencies and disturbthe vehicle's overall aesthetical appearance. Additional components mayalso be required to connect separate vehicle components to one another,which may add to the overall weight of a vehicle.

Many vehicles also have opaque regions around edges of their windows inorder to conceal rubber seals, wires and/or adhesives. For example, avehicle may have window may include an outer fritted region or a regionhaving a dot pattern. These opaque regions are typically formed of athin layer of adhesive film. Over time, however, the adhesive behindthis thin layer of film may wear away and the film may detach from thesurface of a window, thereby deteriorating the component's overallaesthetic appeal and/or exposing concealed components.

The present disclosure aims to solve these problems and other problemsin the prior art.

DESCRIPTION

Aspects of the disclosure will now be described in detail with referenceto the drawings, wherein like reference numerals designate identical orcorresponding parts throughout the several views, unless specifiedotherwise.

Systems and methods disclosed herein provide a tailgate or lift gateand, in particular, a tailgate having a plastic glazing having aone-piece monolithic construction. The one-piece monolithic structurecan be fabricated in one piece using an injection molding process.Vehicles of a hatchback or van configuration typically include an accessopening at their rear and a tailgate that selectively opens and closesthe access opening. The tailgate may be mounted on the main body of thevehicle using a hinged connection. As such, the tailgate may operatelike a hinged flap, which swings open and close along the hingedconnection. The tailgate is typically operated manually but may also beoperated electronically using a power actuator.

The tailgate may support one or more other vehicle components such as arear window, a logo or marking, a light assembly or unit, a licenseplate holder, etc. These components are usually attached to the tailgateusing screws or other connectors or an adhesive. In its closed position,the tailgate may also be adjacent to one or more cavities in the body ofthe vehicle for receiving a rear lamp unit or other light unit.

In order to reduce the number of separate components of a vehicle,systems and methods disclosed herein may provide an integrated tailgateassembly including and/or integrating one or more other vehiclecomponents. For example, systems and methods disclosed herein mayprovide a tailgate having a plastic glazing including a rear window. Theplastic glazing of the tailgate may be constructed of a thermoplasticpolymer including a portion that is clear as the rear window. In othersystems and methods disclosed herein, additional vehicle components mayalso be included in the plastic glazing. Such components may include,for example, a colored translucent portion for a rear light unit; anadditional translucent portion for a courtesy light, a license platelight, or other light unit; a cavity and fixation unit (e.g., a threadedhole, a hook or clip) for supporting a light unit; a cavity and fixationunit for supporting a license plate; a textured and/or raised region fora logo or other marking; a spoiler or other aerodynamic feature; anopening that serves as a ventilation opening; and the like.

Systems and methods disclosed herein may also provide a tailgate thatreduces a number of inhomogeneities, seams, and other disruptions,interruptions, and gaps along a surface of a vehicle, thereby increasingan aesthetic appearance of the vehicle and increasing aerodynamicperformance. Systems and methods disclosed herein further may provide atailgate that conceals one or more other features of a vehicle, such as,for example, a light unit, thereby increasing an aesthetic appearance ofthe vehicle.

Systems and methods disclosed herein may also provide a method ofmanufacturing a tailgate or, specifically, a plastic glazing of atailgate. Such systems and methods may provide a method of producing aplastic glazing using multi-shot injection molding techniques. Forexample, in certain aspects of the disclosure, a plastic glazing of atailgate may be formed via a three-shot injection molding process. In afirst shot, a clear thermoplastic polymer may be injected to form ashell or outline of the plastic glazing. In a second shot, a coloredthermoplastic polymer may be injected to form one or more coloredregions in the plastic glazing. For example, a red thermoplastic polymermay be injected to form a red translucent region to serve as the lensfor a rear light of a vehicle. In an additional shot, a non-transparentthermoplastic may be injected to form a blackout region (e.g., opaque orsubstantially opaque region) of the plastic glazing. The blackout regionmay form a border around a rear window.

Systems and methods disclosed herein may also provide a plastic glazingof a tailgate having a textured surface or a pattern. The texturedsurface or pattern may be disposed on a window or adjacent to a windowformed in the plastic glazing. The window may be formed by a cleartranslucent portion of the plastic glazing. The textured surface orpattern may conceal one or more other vehicle components, such as, forexample, electric wiring. The textured surface or pattern may alsoconceal any adhesive of fixation mechanisms used to attach the plasticglazing to a housing unit or other component of the tailgate. In certainaspects, the textured surface or pattern may be provided on an interiorsurface of a portion of the plastic glazing near the edges of thewindow. In certain aspects, the textured surface or pattern may beformed by a non-transparent thermoplastic polymer forming a blackoutregion on or adjacent to the window. In other aspects, the texturedsurface or pattern may be formed by a translucent thermoplastic polymerthat forms the window. In still other aspect, the textured surface orpattern may be formed by a film disposed on a thermoplastic layer of theplastic glazing.

Referring now to FIG. 1 , an exemplary plastic glazing 100 of a tailgateof a vehicle is depicted. The plastic glazing 100 may be a one-piecemonolithic structure formed of one or more thermoplastic polymers.Examples of suitable thermoplastic polymers include: polycarbonate,polyester carbonate, poly methyl methacrylate, and the like. Accordingto a preferred aspect of the disclosure, the plastic glazing 100 may beformed of a polycarbonate. The plastic glazing 100 can have an outersurface that is seamless, i.e., lacking any visual openings, junctions,disruptions, interruptions, gaps, or the like.

The plastic glazing 100 has a first colored portion 102 that functionsas a portion of a right tail lamp of the vehicle, and a second coloredportion 104 that functions as a portion of a left tail lamp of thevehicle. In particular, the colored portions 102, 104 can function aslenses of the tail lamps of the vehicle. The plastic glazing 100 alsohas a third portion 106 for an additional light unit such as, forexample, an axillary brake light or a courtesy light. The plasticglazing 100 also includes a clear translucent portion 108 that functionsas a rear window of the vehicle, and a colored non-transparent portion110. The colored non-transparent portion may be strategically placed tohide one or more structures positioned behind the plastic glazing 100.

Referring now to FIG. 2 , a housing unit 200 of a tailgate is depicted.The housing unit 200 may be formed of a fiber-reinforced polymer.According to a preferred aspect of the disclosure, the housing unit 200may be formed of a long-glass fiber-reinforced polypropylene such as,for example, SABIC® STAMAX™ plastic. As depicted in FIG. 2 , the housingunit 200 comprises one or more cavities for receiving a light unit. Inparticular, the housing unit 200 comprises a first cavity 212 forreceiving a first light unit 202, a second cavity 214 for receiving asecond light unit 204, and a third cavity 216 for receiving a thirdlight unit 206. The light units 202, 204, 206 can be fixed directly ontothe housing unit 200 via access doors and/or using mechanical fasteners(e.g., screw, bolt, and the like). The cavities 212, 214, 216 canprevent light from the light units from bleeding outside of a confinedspace. As such, additional cavities (not depicted) may be formed next tothe cavities 212, 214, 216 for holding additional light units, and thecavities would prevent the light generated by one light unit frombleeding into a space reserved for another light unit.

The light units 202, 204, 206 may be a single type of light unit. Forexample, the light units 202, 204, 206 can be brake light units.Alternatively, the light units 202, 204, 206 may comprise more than onekind of light unit. For example, the light units 202, 204 can be brakelight units, and the light unit 206 can be a courtesy light unit.

The plastic glazing 100 may be secured to the housing unit 200 such thatthe light units 202, 204, 206 are disposed between the plastic glazing100 and the housing unit 200. In particular, the plastic glazing 100 maybe secured to the housing unit 200 such that the light units 202, 204,206 are disposed behind the portions 102, 104, 106 (depicted in FIG. 1). The light unit 202 may be disposed behind the first colored portion102, the light unit 204 may be disposed behind the second coloredportion 104, and the light unit 206 may be disposed behind the thirdportion 106.

Light emitted from the light units 202, 204, 206 through the portions102, 104, 106 of the plastic glazing 100 may be emitted as a coloredlight in accordance with certain international standards governingvehicle lighting such as, for example, ECE Regulation No. 48 and SAEStandard J578. As noted above, the portions 102, 104 can function as thelens for the vehicle's tail lamps. Accordingly, light emitted from thelight units 202, 204 through the portions 102, 104 may be red. ECERegulation No. 48 defines the color “red” as emitted light withchromaticity coordinates (x,y) that lie within the chromaticity areasdefined by the following boundaries in the CIE xyY color space:

R₁₂ yellow boundary: y = 0.335 R₂₃ the spectral locus R₃₄ the purpleline R₄₁ purple boundary: y = 0.980-xWith the following (x,y) intersection points:

-   -   R₁: (0.645,0.335)    -   R₂: (0.665,0.335)    -   R₃: (0.735,0.265)    -   R₄: (0.721,0.259)        Thus, to fulfill this regulation, the light emitted through the        portions 102, 104 may have chromaticity coordinates (x,y) that        fall within the chromaticity area defined for the color red in        ECE Regulation No. 48, as set forth above.

While the portions 102, 104 and the light units 202, 204 are describedherein as producing a red light, one of ordinary skill in the art wouldappreciate that the portions 102, 104 and the light units 202, 204 mayalso be designed to produce lights having other colors, such as, forexample, yellow or amber. These colors are also defined in ECERegulation No. 48 as well as in other international standards.

The housing unit 200 also includes an opening 208. When the plasticglazing 100 is secured to the housing unit 200 such that the light units202, 204, 206 line up with the portions 102, 104, 106, the opening 208may line up with the clear translucent portion 108 of the plasticglazing 100. By lining up with the clear translucent portion 108, theopening 208 allows an individual's view through the translucent portion108 (which, as described above, may function as the rear window of thevehicle) to remain unobstructed.

Each of the light units 202, 204, 206 may include one or more lightcomponents such as, for example, an incandescent lamp, anelectroluminescent lamp, a gas discharge lamp, and the like. Because thelight units 202, 204, 206 are secured directly onto the housing unit200, a separate housing for each light unit 202, 204, 206 may not beneeded. Thus, the housing unit 200, which serves as the structuralcarrier for the plastic glazing 100 of the tailgate, integrates ahousing function of a light unit. Moreover, because the portions 102,104, 106 may function as the lens of a light unit—i.e., the portion 102may function as the lens for the light unit 202, the portion 104 mayfunction as the lens for the light unit 204, and the portion 106 mayfunction as the lens for the light unit 206—a separate lens for eachlight units 202, 204, 206 also may not be needed.

The plastic glazing 100 may be secured to the housing unit 200 using anadhesive and/or a mechanical fastening system (e.g., a screw bolt orclip fastening system). The adhesive used may be a commerciallyavailable adhesive that is typically used in the automotive industry forthe adhesive bonding of plastic components. Such adhesives may include,for example, wet adhesives, contact adhesives, hot-melt adhesives, orreaction adhesives. The thickness of the adhesive required may varydepending on the specific geometries of the plastic glazing 100 and thehousing unit 200. When the adhesive is a hot-melt adhesive that can beprocessed under thermoplastic conditions, it may be possible to bond theplastic glazing 100, the housing unit 200, and the hot-melt adhesivetogether during a multi-shot injection molding process.

While the tailgate including the plastic glazing 100 and the housingunit 200 is depicted as having three light units 202, 204, 206, one ofordinary skill in the art would appreciate that the tailgate cancomprise less or more light units. Such light units may include, forexample, license plate lamps, turn signal lamps, backup lamps, and thelike.

Referring now to FIG. 3 , an exemplary plastic glazing 300 of a tailgateof a vehicle is depicted. The plastic glazing 300 may be similar to theplastic glazing 100 depicted in FIG. 1 but may include additionalsections 312, 314. The plastic glazing 300 may be of one-piecemonolithic molded plastic construction, and may have an outer surfacethat is substantially free of any inhomogeneities, seams, and otherdisruptions, interruptions, and gaps.

The plastic glazing 300 may have two colored translucent portions 302,304 that function as lens of tail lamp units of the vehicle. The plasticglazing 300 may also have an additional clear or colored portion 306that functions as a lens of an additional light unit. The plasticglazing 300 may further have a clear translucent portion 308 thatfunctions as a rear window of the vehicle, and a non-transparent portion310. The non-transparent portion 310 may surround the clear translucentportion 308, thereby outlining the rear window of the vehicle. Theplastic glazing 300 may also have sections 312, 314, which may include atextured surface and/or a pattern.

While the plastic glazing 300 is depicted with two sections 312, 314that may include a textured surface or a pattern, one of ordinary skillin the art would appreciate that a plastic glazing such as the plasticglazing 300 of FIG. 3 can include sections other than the sections 312,314 that may include a textured surface or a pattern. Such sections, forexample, may be disposed along a top of bottom edge of a translucentportion corresponding to the rear window. Thus, sections 312, 314 andany such additional sections may form a continuous region surrounding atranslucent portion corresponding to the rear window of the plasticglazing. Moreover, one of ordinary skill in the art would appreciatethat the section 312, 314 may be wider or narrower, or comprise adifferent shape, than how they are depicted in FIG. 3 .

FIG. 4 depicts a cross-sectional view of the plastic glazing 300 alongthe line B-B. As depicted in FIG. 4 , the plastic glazing 300 maycomprise multiple thermoplastic polymers. The plastic glazing 300 maycomprise a clear translucent component 320, a dark component 322, and acolored component 324. The dark component 322 may be black (e.g.,blackout) or be another color and/or effect. Each component may beformed by a different thermoplastic polymer such as, for example,different colored polycarbonate resins. The translucent component 320may be formed of a clear thermoplastic polymer to provide a clearunobstructed view there through. In certain aspects, the translucentcomponent 320 may comprise a certain degree of color but nonethelessretain sufficient transparency to allow a high degree of lighttransmittance. For example, the translucent component 320 can comprise atint, such as a grey, green, or brown tint. The dark component 322 maybe a black or other colored non-transparent thermoplastic polymer thatis configured to control light transmission through the translucentcomponent 320. In particular, the dark component 322 may be optimallypositioned on the plastic glazing 300 to conceal one or more vehiclecomponents disposed behind the plastic glazing 300 such as, for example,a housing unit. The dark component 322 may also conceal any adhesive orfixation mechanisms used to attach the plastic glazing to a housing unitor other component of the tailgate.

The translucent component 320 may be in a first layer, and the darkcomponent 322 and the colored component 324 may be in a second layerseparate from the first. The translucent component 320, the darkcomponent 322, and the colored component 324 may have the same thicknessor different thicknesses. In an aspect of the disclosure, thetranslucent component 320 may have a thickness that is greater than thatof the dark component 322 and the colored component 324. The translucentcomponent 320 can have a greater thickness in order to providestructural strength to the plastic glazing 300. In another aspect of thedisclosure, the thickness of the dark component 322 may be increased inorder to provide additional structural support to an outer panel of theplastic glazing 300 along which the dark component 322 is disposed.

The translucent component 320 may define a panel or overall shell of theplastic glazing 300. The dark component 322 and the colored component324 may be disposed behind the translucent component 320 towards aninterior of a vehicle. By being disposed behind the translucentcomponent 320, the dark component 322 and the colored component 324 canbe protected from weathering effects. Moreover, the dark component 322and the colored component 324 would not create any inhomogeneities orraised portions on a surface of the vehicle.

A first portion of the clear translucent component 320 that does notoverlap the dark component 322 and the colored component 324 in thelongitudinal direction (i.e., a direction along the line B-B) may formthe translucent portion 308 that functions as the rear window of thevehicle. The colored component 324 and a second portion of the cleartranslucent component 320 that overlaps the colored component 324 in thelongitudinal direction may form the colored portion 304 that functionsas a lens of a tail lamp unit. And the dark component 322 and additionalportions of the clear translucent component 320 that overlap the darkcomponent 322 in the longitudinal direction may form the non-transparentportion 310.

The plastic glazing 300 may be manufactured or produced using aninjection molding technique. In particular, the plastic glazing 300 maybe produced using a three-shot injection molding technique. Thethree-shot injection molding technique may use a mold cavity that can bealtered between different volumes. The mold cavity may be an example ofa molding apparatus. The mold cavity may be set to a first volume forreceiving a first shot of material. The first shot of material may formthe translucent component 320. Accordingly, the mold cavity may be setto a volume corresponding to that of the translucent component 320. Afirst material may be injected into the mold cavity to form thetranslucent component 320. The first material may be a clear,translucent thermoplastic polymer such as, for example, a clearpolycarbonate. After the first shot has been injected, the mold cavitymay be changed from its first volume into a second volume.

The next shot of material may form the colored component 324.Accordingly, the mold cavity can be set to a volume corresponding tothat of the colored component 324. A second material may be injectedinto the mold cavity to form the colored component 324. The secondmaterial may be a similar type of material as the first material so thatheat released by the second material along the edge of the firstmaterial may melt and fuse (i.e., combine) the colored component 324 tothe clear translucent component 320. As such, if the first material is aclear polycarbonate, the second material may be a colored polycarbonate,such as, for example, a red polycarbonate. After the second shot hasbeen injected, the mold cavity can be changed from its second volume toa third volume. The third and final shot of material may form the darkcomponent 322. Accordingly, the mold cavity can be set to a volumecorresponding to that of the dark component 322. Such may involve takinginto account the portion of the cavity already filled by the first andsecond shots. A third material may be injected into the mold cavity toform the dark component 322. The third material also may be a similartype of material as the first and second materials such that heatreleased by the third material along the end of the first and secondmaterials may melt and fuse the other components to the dark component322. After the third shot, the entire molded assembly may be left tocool.

According to certain aspects of the disclosure, the order of the secondshot and the third shot can be changed. Thus, instead of injecting thesecond material to form the colored component 324 in the second shot,the third material for forming the dark component 322 can be injectedduring the second shot. In such aspects, the mold cavity can be adjustedfirst to a volume corresponding to the dark component 322 and then to avolume corresponding to the colored component 324.

FIGS. 5-11 present alternative embodiments of a region labeled A(depicted in FIG. 3 ) of the second exemplary plastic glazing 300. FIGS.5 and 6 show a first embodiment where the section 312 has a texturedsurface. FIGS. 7 and 8 show a second embodiment where the section 312has a pattern. And FIGS. 9-11 show a third embodiment where the section312 has an inverted frit pattern. Each of these embodiments will bediscussed in turn below.

As depicted in FIG. 5 , the section 312 of the plastic glazing 300 has atextured surface. The textured surface is disposed next to thetranslucent portion 308. FIG. 6 shows a cross-sectional view of thesection 312 along line C-C depicted in FIG. 5 . As shown in FIG. 6 , thesection 312 may be formed of a translucent component 400. Thetranslucent component 400 can correspond to the translucent component320 depicted in FIG. 4 . In other words, the translucent component 400may be a separate region of the same translucent component 320. Thetranslucent component 400 may have a textured surface having a pluralityof raised structures 402. In an aspect of the disclosure, the raisedstructures may be microstructures.

The plurality of raised structures 402 may be disposed on a side of thetranslucent component 400 towards an interior of the vehicle. As such,the plurality of raised structures 402 would not be subject toenvironmental factors on the outside of the vehicle. The plurality ofraised structures 402 may reduce a degree of transparency of thetranslucent component 400 due to their influence on the passage of lightthrough the translucent component 400. In particular, the plurality ofraised structures 402 can scatter and/or diffuse light, thereby reducingthe visibility of items disposed on either side of the translucentcomponent 400 from the other side. By reducing the transparency of thetranslucent component 400, the plurality of raised structures 402 canhelp to conceal a vehicle component located behind the section 312. Suchmay include, for example, a housing unit of the tailgate, adhesives orother fixation mechanisms used to attach the plastic glazing to thehousing unit, wires around an edge of a rear window of a vehicle, andthe like.

Because the plurality of raised structures 402 of the textured surfacereduces the transparency of the translucent component 400, it may not benecessary to have a dark component, such as, for example, the darkcomponent 322 described above with respect to FIG. 4 , to black out thesection 312 of the plastic glazing 300. As described above, a darkcomponent (e.g., the dark component 322) that is placed behind atranslucent component (e.g., the translucent component 320) may alsoserve to conceal one or more vehicle component and/or fixationmechanisms behind a region of the plastic tailgate. The addition of thedark component, however, may add to the weight of a vehicle. Moreover,the dark component may completely eliminate the passage of light throughthe translucent component 400 into the interior of the vehicle, therebycreating a darker environment within the vehicle. Such can be avoidedthrough the use of a textured surface, such as the textured surfacedepicted in FIGS. 5 and 6 having the plurality of raised structures 402.The textured surface would be formed on an existing component (i.e., thetranslucent component 400), and therefore would not add to the overallweight of the vehicle. The textured surface can also be adjusted toallow an optimal degree of light through into the interior of thevehicle.

The plurality of raised structures 402 may be formed when thetranslucent component 400 is molded using an injection moldingtechnique. As described above, the translucent component 320 may beformed using an injection molding technique, whereby a first cavity isconfigured to receive a shot of clear translucent material. Similar tothe translucent component 320, the translucent component 400 may beformed using a mold cavity that is configured to receive a shot of cleartranslucent material. The clear translucent material may be, forexample, a clear polycarbonate resin. The mold cavity may comprise asurface having a plurality of indentations that is configured to formthe plurality of raised structures 402. Thus, when the clear translucentmaterial is injected into the mold cavity, the resulting translucentcomponent (i.e., the translucent component 400) would have a surfacehaving the plurality of raised structures 402.

While the textured surface depicted in FIGS. 5 and 6 is shown to have aplurality of lines or ridges, one of ordinary skill in the art wouldappreciate that other types of textures, including textures formed ofdots and other types of structures can also be used.

Referring now to FIG. 7 , an alternative embodiment of the section 312is depicted. The section 312 depicted in FIG. 7 has a pattern. FIG. 8depicts a cross-sectional view of the section 312 including the pattern.As depicted in FIG. 8 , the section 312 may comprise a translucentcomponent 502 and a patterned film 506.

The translucent component 502 may correspond to the translucentcomponent 320 depicted in FIG. 4 (i.e., be a separate region of the sametranslucent component 320). The patterned film 506 comprises thepattern, which is visible through the translucent component 502 (asshown in FIG. 7 ). The patterned film 506 can be disposed behind thetranslucent component 502 towards an interior of the vehicle.

Similar to the textured surface described with respect to FIGS. 5 and 6, the pattern of the patterned film 506 may also conceal a vehiclecomponent located behind the section 312. Such may include, for example,a housing unit of the tailgate, adhesives or other fixation mechanismsused to attach the plastic glazing to the housing unit, wires around anedge of a rear window of a vehicle, and the like. The patterned film mayinclude translucent and non-transparent portions. The patterned film mayallow for the inclusion of complex patterns that may not be easilyinjection molded using a single-colored component such as, for example,a dark component (e.g., the dark component 322). The patterned film mayalso remove the need for a dark component (e.g., the dark component322), which may reduce an overall weight of the vehicle.

The section 312 may be formed as part of an injection molding processfor forming the plastic glazing 300, similar to the one described abovewith respect to FIG. 4 . The specific type of injection molding processmay be referred to as film insert molding, also known as in-molddecoration. Each of the translucent component 502 and the patterned film506 may be a polycarbonate resin or other thermoplastic polymer. In apreferred aspect, both components are formed using the samethermoplastic polymer to enable optimal bonding between the separatecomponents.

The pattern on the patterned film 506 may be ink printed onto a firstsurface. The ink printed onto the first surface of the patterned film506 may comprise a polymer resin such as, for example, a polycarbonateresin. The ink may be applied onto the first surface of the patternedfilm 506 via screen printing, although other method of printing known tothose skill in the art are also acceptable, such as but not limited tomask/spray in-jet, and pad or tampon printing. Once the ink is printed,drying should be thorough to ensure that any retained solvent is removedfrom the print. Residual or retained solvent may cause problems at alater stage with cracking/crazing of the polycarbonate itself due tosolvent damage. The inks may be thermally cured by being exposed to anelevated temperature for a period of time. For example, a printed inkcan be substantially cured upon exposure to about 90-125° C. for about20-60 minutes. The thickness of the cured ink print is typically about 4micrometers to 20 micrometers, with between about 8 micrometers to 18micrometers being preferred.

After the ink pattern has been applied to the patterned film 506, thepatterned film 506 may be trimmed to a desired shape. For example, thepatterned film 506 may be trimmed such that it conforms to an areacorresponding to the section 312. In a preferred aspect of thedisclosure, the thickness of the patterned film 506 is approximately0.05 to 2 millimeters. The small thickness allows the patterned film 506to be shaped prior to being bonded to one or more other components(e.g., the translucent component 502).

The patterned film 506 can be placed into a first mold cavity forreceiving a material for forming the translucent component 502. Sincethe section 312 does not cover an entire surface of the translucentcomponent 320 (of which a region is the translucent component 502), thepatterned film 506 may only cover a portion of the first mold cavity.The patterned film 506 may be placed into the mold cavity such that theprinted ink pattern is disposed towards a wall of the cavity. Throughsuch placement, the ink pattern may be shielded from the heat of theshot of material forming the translucent component 502. The patternedfilm 506 may be held to the wall of the cavity by vacuum or any othermeans known to those skilled in the art of film insert molding.

When the shot of material for forming the translucent component 502 isinjected into the mold cavity, it would bond with a second surface ofthe patterned film 506 that does not have the ink pattern. In apreferred aspect where the translucent component 502 and the patternedfilm 506 are both the same type of thermoplastic polymer, the heat fromthe shot of material forming the translucent component 502 may melt thefilm layer, thereby causing the two layers to bond together when theycool. The first mold cavity can be adjusted to a second mold cavity(i.e., the volume of the mold cavity may be changed from a first volumeto a second volume).

Referring now to FIG. 9 , another alternative embodiment of the section312 is depicted. The section 312 depicted in FIG. 9 has a halftonepattern, such as, for example, an inverted frit or dot pattern. FIG. 10depicts a cross-sectional view of the section 312 including the halftonepattern. As depicted in FIG. 10 , the section 312 comprises atranslucent component 602 and a dark component 604. The translucentcomponent 602 may correspond to the translucent component 320 depictedin FIG. 4 (i.e., be a separate region of the same translucent component320). The dark component 604 may correspond to the dark component 322depicted in FIG. 4 (i.e., be a separate region of the same darkcomponent 322).

The dark component 604 may be formed in the shape of the halftonepattern. The dark component 604 can be disposed behind the translucentcomponent 602 toward an interior of the vehicle. The dark component 604can be bonded to the translucent component 602 in an injection moldingprocess. Such a bonding process may comprise a polymerization where amolecules of the first material and molecules of the second materialreact together to form polymer chains.

As described above, a multi-shot injection technique may be used to formthe plastic glazing 300. In a first shot, a clear translucent materialmay be injected into a mold cavity having a first volume to form thetranslucent component. After the clear translucent component is formed,the mold cavity may be adjusted to a second volume and so on and soforth for receiving additional shots of material. In a second shot (or athird shot), a black or other colored opaque material may be injected tothe mold cavity such that it binds with the clear translucent material.The two materials may bind together through melt bonding. That is, heatfrom the injected opaque material may melt a surface of the already setclear translucent material such that a bond is formed between the twomaterials when they cool down. With respect to the translucent component602 and the dark component 604 depicted in FIG. 10 , the same procedurecan be used. The shape of the dark component 604 (or the section 312)may be formed by using a mold cavity that has a volume that isaccordingly shaped.

The inverted frit pattern of FIG. 9 may be formed using a singlecontinuous section of the dark component 604. In contrast, a traditionalfrit pattern, which includes a number of separate dot formations, wouldrequire a plurality of separate injection points. The inverted fritpattern of FIG. 9 , while achieving a similar purpose as the traditionalfrit pattern, removes the need for having multiple injection points.

While the halftone pattern depicted in FIG. 9 is an inverted dotpattern, one of ordinary skill in the art would recognize that otherhalftone patterns, both inverted and non-inverted, can be used. Such apattern may also be designed such that it allows the formation of asingle connected region of blackout (e.g., the dark component 604).

According to certain aspects of the disclosure, the tailgate assemblesdisclosed herein may also include additional layers on top of thethermoplastic polymer layers. For example, a protective layer such as aweathering layer may be added to a surface of the plastic glazing. Anexample of such a layer is depicted as item 606 in FIG. 11 , where sucha layer is applied to an interior surface of the plastic glazing. Inalternative aspects, such a layer may be applied to both the interiorand exterior surface of the plastic glazing, or to only the exteriorsurface of the plastic glazing. The layer preferably comprises either apolyurethane coating or a combination of an acrylic primer and asilicone hard-coat. Alternatively, other coating systems may be used. Anexample of such an acrylic primer includes Exatec® SHP 9X, which iscommercially available from Exatec, LLC (Wixom, MI) and distributed byGeneral Electric Silicones (Waterford, NY). In one preferred embodiment,the primer is coated on the plastic glazing of the tailgate, air dried,and then thermally cured between about 80° C. and 130° C. for betweenabout 20 to 80 minutes and more preferably at about 120° C. for about 60minutes. A silicone hard-coat is then applied over the primer layer andis air dried before curing at preferably between about 80° C. and 130°C. for between about 20 to 80 minutes and more preferably at about 100°C. for about 30 minutes. A preferred silicone hard-coat used in thepresent invention is available from Exatec, LLC and distributed byGeneral Electric Silicones as Exatec® SHX.

As another example, an abrasion resistance layer can also be applied toa surface of the plastic tailgate or even to another protective layer,such as the weathering layer described above. Specific examples ofpossible inorganic coatings comprising the abrasion resistant layerinclude, but are not limited to, aluminum oxide, barium fluoride, boronnitride, hafnium oxide, lanthanum fluoride, magnesium fluoride,magnesium oxide, scandium oxide, silicon monoxide, silicon dioxide,silicon nitride, silicon oxy-nitride, silicon oxy-carbide, siliconcarbide, hydrogenated silicon oxy-carbide, tantalum oxide, titaniumoxide, tin oxide, indium tin oxide, yttrium oxide, zinc oxide, zincselenide, zinc sulfide, zirconium oxide, zirconium titanate, or glass,and mixtures or blends thereof. The abrasion resistant layer may beapplied by any technique known to those skilled in the art. Thesetechniques include deposition from reactive species, such as thoseemployed in vacuum-assisted deposition processes, and atmosphericcoating processes, such as those used to apply sol-gel coatings tosubstrates.

As another example, an additional layer for adding more support to thethermoplastic polymer layers may also be added to an interior surface ofthe plastic glazing. This additional layer may be formed of a plastic, ametal, or other material for increasing the structural strength of thetailgate.
